CartoGrid · x402
Turn game cartography into an active revenue stream. A map server where every 'Fog of War' reveal, POI zoom, or quest-layer toggle is a $0.01 micro-transaction. Creators host the data; players pay as they explore. Integration-ready for indie RPGs via HTS transfer, enabling game engines to query high-fidelity map data one tile at a time without upfront subscriptions.
The primitive.
Access to the game world mapping engine is metered with x402: 0.01 HBAR or 0.01 HTS USDC per call, paid from the embedded wallet, so game designers — or the agents working for them — pay per query and get a HashScan receipt every time.
Why this primitiveShifts 'ownership' (NFT) to 'utility' (Pay-per-query). Instead of buying a static asset once, developers or players pay to stream the cartography data as needed, ensuring creators are paid for every session of exploration rather than a one-time minting event.
